If we want to see all of the tapes in a jukebox, we can simply use the juke command "list":
% juke
> list jukebox sga
default drive: d0
default slot: s0
default port: p0

The listing shows our default slot, port, and drive, and then has column listings for all the locations in the jukebox. The first column, labelled "NAME" shows the tape name (if any) associated with media in that location. "(empty)" in this column indicates that the jukebox does not think it has media in that location (this may or may not correspond with reality, especially if the jukebox has been opened and media have been taken in and out).
The second column shows what the location is called, including a drive name alias for the drives.
The third column lists a "hop count" which says how many times the media has been moved around the jukebox.
The last column is the date when the tape in this location was last renamed, which is our best guess for when it was put into the jukebox.
